The wife unexpectedly approved a SVS PB12-Plus, ...before I pull the trigger, are there better options?

Budget $1,400 or less
75% movies/TV 25% music
I don't have room for 2 subs at this point
Looks do have a small part in the decision making
I currently have an A-2 300, which doesn't cut the mustard for music.
I want to be able to feel the punch in my music (Hard rock) and be able to play the lows when watching movies without worrying about damaging the sub
I don't watch movies at reference levels but I do occasionally for music
It will be connected to an Onkyo TX-NR 809 with Klipsch Reference surround (RF 82 towers in the front)

Room details
About 3500 cubic ft (not a square room)
4 walls and one door opening (no door)
2 walls are brick the other 2 are glass (floor to ceiling windows)
Tile floor
Tongue and groove ceiling
No room correcting sound treatments, most likely never will be in this room

Having a smoking section in a restaurant is like having a peeing section in a pool.

The Rythmik is a solid choice.
The other interesting choice would be the Power Sound Audio XS30. The XS30 will give you plenty of slam for music while still giving you a smooth rolloff down to below 20Hz for movies

+1. Those would be my votes as well. WAF wise, the SVS (IMHO) is probably the best looking but these other options offer more bang for the buck.

I've had my PB12-Plus (black oak) for just over a year. I've never heard the Rythmik but with all the endorsements, it's got to be solid. Many say the current PB12-Plus performs on par with the previous PB13-Ultra with the Bash amp. My room is approx. 3500 cu. ft. and open to other rooms. Most of our use is home theater and the PB12 will amaze....the train wreck in Super 8 scared the schitt out of my family. The fit and finish is top shelf and the 5 year warranty on everything is very reassuring. The DSP Sledge amp is really nice and you don't have to worry about overdriving it. Check the Audioholics review.

If you could find the Seatons Submersive-Hp or (non HP version) in the used market, I would consider that above the SVS and Rhythmic. The Submersive can play as clean as the Rhythmic and can go much deeper and louder even than the PB13Ultra(except at its tuning freq, which is 20hz). Else you can also look for the JTR Captivator Passive in the used market. These 2 subwoofers will outperform most of the great subwoofers.
